In the previous article, I drew on Václav Havel's The Power of the Powerless to explore why so many of us have become numb to injustice. In this article, I turn once again to history to ask a different question: who must lead the change? 

What do Ernesto "Che" Guevara, Rudolf Virchow, Norman Bethune, Muthulakshmi Reddy, and Binayak Sen have in common? Each was a physician who refused to believe that medicine ended at the bedside. They recognized that suffering is often rooted in injustice, and they dedicated their lives to confronting both. 

Why doctors can lead the way

Physicians occupy a rare position in society. They are entrusted with intimate access to people's lives at moments of profound vulnerability while simultaneously commanding a level of public credibility that few professions enjoy. 

Every day, they witness how decisions made in legislatures, ministries, and boardrooms manifest as illness in clinics and hospitals. They see poverty translated into malnutrition, polluted environments into chronic disease, contaminated medicines into the death of their patients, and exam paper leaks into self-harm. This direct encounter with the consequences of structural inequities and injustices gives physicians a perspective that extends well beyond prescription-driven healthcare.

Because their observations emerge from lived clinical experience, doctors often carry moral authority across political and social divides. Their testimony resonates in courtrooms, policymaking forums, the media, and public discourse. Few professions are as well-positioned to demonstrate that many illnesses are not simply biological events but the predictable outcomes of political, economic, and social choices made by those in power.

This understanding has deep historical roots. 

For Rudolph Virchow, a German pathologist, medicine could never be separated from politics. Investigating a typhus epidemic in Upper Silesia in 1848, he concluded that the outbreak was driven not by biology alone but by poverty, poor housing, hunger, illiteracy, and political exclusion. Health, he argued, could not be improved through medical treatment alone. It required transforming the conditions in which people lived.

The same year, Virchow co-founded Medical Reform, a weekly journal through which he advanced two ideas that would define social medicine: that "medicine is a social science" and that "physicians are the natural attorneys of the poor." These were not merely philosophical statements. They were a call for doctors to recognise that disease is inseparable from inequality and that medical practice carries an obligation to challenge the structures that produce suffering.

Virchow acted on these convictions throughout his career. In 1861, he helped establish the German Progressive Party and entered the Prussian parliament, where he became a prominent critic of Otto von Bismarck's militaristic agenda. He repeatedly argued that governments should invest in sanitation, education, housing, and clean water rather than military expansion, viewing these not as social welfare programmes but as essential public health interventions.
